   A developer is creating test data for a class that requires a hierarchy of records: Account, Contact, and Case. The developer wants to ensure the data is created consistently across multiple test classes. Which approach best achieves this?

   • AUse Test.loadData to load all three objects from a static resource.
   • BInsert the records directly in each test method.
   • CCreate a Test Data Factory that builds the Account, Contact, and Case with proper relationships.
   • DUse @testSetup in each test class to create the hierarchy.

   What is the primary benefit of using a Test Data Factory pattern?

   • AIt ensures test data is always isolated from org data.
   • BIt automatically generates test data from production data.
   • CIt speeds up test execution by using parallel processing.
   • DIt reduces code duplication and improves maintainability of test data creation.

   A developer is testing a class that makes an HTTP callout and then updates a record based on the response. The test needs to verify that the record is updated correctly. The developer has set up an HttpCalloutMock. What additional step is required to ensure the test is reliable?

   • AUse Test.startTest and Test.stopTest around the callout and the update.
   • BUse Test.loadData to load the record to be updated.
   • CUse SeeAllData=true to access the record that needs updating.
   • DUse WebServiceMock to mock the callout.
